Final answer:
When an applicant applies to all specialties mentioned in an announcement, they must be referred to each specialty if they meet the qualifications, ensuring every specialty is aware of all potential applicants.
Step-by-step explanation:
In scenarios where an announcement is made for multiple specialties, and an applicant applies for all specified specialities, standard procedures typically require the referral of the candidate to each specialty for which they have shown interest and met the qualifications. This process ensures that each department or specialty area considering candidates is aware of all potential applicants. Thus, if the applicant's qualifications align with the requirements of the specialties, they must be referred for considering their candidacy in all relevant areas.
